Wireless Device Security

You recently bought a smart thermostat for your home. It lets you control the temperature remotely using a mobile app. With the security of your new smart thermostat in mind, which of the following actions would be the LEAST effective for protecting it against unauthorized access?

  • A Keeping the thermostat firmware updated with the latest security patches from the manufacturer.
  • B Changing the default password for the mobile app and thermostat upon initial setup.
  • C Enabling remote access to the thermostat only on your secure home Wi-Fi network.
  • D Leaving the thermostat connected to the “Guest” Wi-Fi network in your home, which is open to all guests.
Explanation

An open guest Wi-Fi network allows untrusted guest devices onto the same network segment as the thermostat, increasing the opportunity for unauthorized devices to discover or attack it. Keeping firmware patched, changing default credentials, and limiting access to a secured network all reduce unauthorized-access risk.
